NITED STATES "CHARLES J. ADDY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THETAPLEY MACHINE COMPANY.

BURNlSHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 303,383, dated August12, 1884.

Application filed June 23. 1884. (No model.)

' Boston, in the county of Suffolk and State of Massachusetts, haveinvented an Improvement in Burnishing-lvlachines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention has for its object the production of a machine whereinthe heel may be burnished frombreastto breast in one and then in theother direction by a rotating burnishing-tool, the said tool rotating infirst one and then in the other direction as the shaft carrying it ismoved bodily about the heel.

My invention consists, essentially, in a rotating burnishing-toolconnected with an actuating-shaft therefor, mounted in ayielding car-'rier which is adapted to be moved about the heel, combined withmechanism to rotate the said tool in one and then in the opposite direction as the said tool is moved about the heel, and then back again bythe yielding carrier. The tool has a motion of rotation on its own axis,and its axis or hearing is revolved about the heel in a pathcorresponding with the curvature of the latter, and when moving from onebreast toward the other in one direction the tool is rotated toward theleft, and when the said yielding carrier is being moved back in theopposite direction the tool is rotated toward the right.

Figure 1 represents in side elevation a burnishing-machine embodying myinvention, the stationary gear and tool being partially broken out toshow their construction; and Figs. 2 and 3 arediagrams, to be referredto, showing the heel and the direction of rotation of th tool about andin contact with it.

The standard A, provided with uprights A A A A the foot-lever A the jackB, provided with the shoulder a for the breast of the heel, the rest afor the top-lift, and the adj ustable presser a to act within the shoeand hold it on the jack while the heel of the boot or shoe is beingburnished, the guide 0 for the jack, the driven shaft D, its attachedcrank d, link d, vibrating sector or bell-crank lever (1 having itsfulcrum on bolt 3, gear 0 fast on the shaft 6, supported in bearings-inthe uprights A A, and counter-balance e, are all substantially as in thewell-known Ta 1e burnishin P Y a:

machine in market, so said parts need not be herein further described.

The stud 3, which serves as the fulcrum for thelever d", is herein madeto hold the upright m, to which is bolted by bolts m the toothed rack orinternal gear, m, having a series of teeth, in, at the inner side of itsflange. (See Fig. 1.)

The shaft 0', which has a rotary reciprocating movement, has attached toit by screw 2 the "frame h, having as part of it the bearing or sleeveh, which latter receives the part h 1 of the tool-actuating shaft h,having at one end; a gear, h, which is made to engage the teeth m.

The part h of the tool-actuating shaft is what is known as flexible orstow-shafting,

and the said shaft, being extended to the bearing f, has operativelyconnected with it the rotating burnishing-tool 9, provided at itsperiphery with a series of corrugations, as shown at 4." The bearing ffor the burnishing-tool or its shaft is attached to the bearing-carrierf, pivoted by bolt f to the block h, so that the said carrier is free toyield or turn on the said bolt as the bearingcarrier and tool-actuatingshaft are moved about the heel from breast to breast and back again bythe shaft 0.

The tool 9 may be heated in any usual manner. Herein I have shown agas-pipe, a, of usual construction. 7

As the shaft 6 is rotated, first in one and then back in the oppositedirection, the frame h, its attached bearing h, the bearing-carrierf,bearing f, tool-actuating shaft, and the gearing h are carried or movedwith it, and the gear h in engagement with the internal teeth, m", ofthe stationary gear or rack m, effects the rotation of shaft h k andwith it the tool y.

In Fig. 2 I have shown the outline of a heel the corner 5. Theburnishing-tool having arrived at the breast 6, while the sectororle-ver d was moved in one direction, the said sector or lever isvibrated in the opposite direction,

5 to effect the movement of the gear 6. shaft 6,

and its attached parts in the opposite direction, thus moving the toolgabout and in contact with the heel .from the corner 6 of ,the breast tothe corner 5 but duringthe backward movement of the said tool the gear hin engagement with the teeth m effects the rotation in the reversedirection of the tool-carrying shaft and tool, their direction ofrotation at such time being shown by the curved arrow in Fig. 3, whichit will be noticed is just opposite that of the curved arrow in Fig. 2,the said tool, when acting on the heel from the corner 6 to the corner5, rubbing the heel from the corner 6 backward. This reverse rotation ofthe tool is due to change in the di-. rection of the movement of theshaft 63116.3

its attached parts, which rolls the toothed wheel h over the stationaryteeth on in first one and then in the opposite direction;

The counter-balance has a roll or pin, 13, (shown in dotted lines,) onwhich acts the spring 14, connected by bolt 15 with the block 71,- thesaid spring thus acting to keep the bearing-carrier f down so as topress the tool against the edge of the heel with the desired pressure.

The descent of the bearing-carrier f is determined or regulated by meansof a bolt, 16, screwed-into the said carrier, the head of the boltmeeting the shaft 0, a check-nut, 18, holding the bolt in place.

The outside shape of the tool 9 will be adapted in curvature or shape toconform to the heel to be burnished.

1; In a heeLburnishing machine a rotating burnishing-tool connected withanactuatingshaft therefor, mounted in a yielding carrier adapted to bemoved about the heel, combined with mechanism, substantially asdescribed, to rotate the said tool in one and. then in the oppositedirection, as the said tool is moved about the heel from one to theother corner of the breast of the heel and then back, substantially asset forth.

2.-In a burnishing-machine, a rotary reciprocating shaft, an attachedbearing-frame, a rotary shaft, an attached rotary burnishingtool, ayielding carrier for the tool-actuating shaft, and a gear connected withthe said shaft, combined with a series of teeth to be engaged by thesaid toothed gear, whereby the toolactuating shaft is rotated first inone and then in the opposite direction, substantially as de scribed.

3. The bearing f, made movable in a curved path about the heel, and theburnishing-tool, and a shaft to rotate it, combined with a gear, and'aseries of teeth, on, along and in en agement with which the said gear isma e to travel as the tool is carried about the heel, whereby the saidtool is rotated in opposite directions, as set forth. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
